Title: Checking acceptance of a string by automaton
Inventor: WATANABE YUJI
IPC: G06F9/44
Filed: 2012-12-07
Abstract: Provided is a server (30), connectable to a client (20) for input of a string, having an automaton whose state transitions in accordance with received characters, and determining whether the automaton has transitioned to a final state on the basis of the characters. The server receives from the client in the characters included in the string a coding sequence whose elements corresponding to the characters are values encrypting a non-unity using a first encryption scheme having homomorphism, and whose elements not corresponding to the characters are values encrypting a unity using the first encrypting scheme; generates, in response to receiving the coding sequence, exchange data encrypting a subsequent state key corresponding to each of a plurality of previous states of the automaton on the basis of the coding sequence using the first encryption scheme; encrypts exchange data with the corresponding previous state key; and sends the encrypted exchange data to the client. The first encryption scheme may have additive or multiplicative homomorphism. The exchange between client and server occurs in an oblivious fashion such that the string is not revealed to the server in plaintext and the servers    automaton is not revealed to the client. The arrangement may be used to verify a password or PIN input by a client, for example.

Filed: 2012-08-08
Abstract: Load balancing in an enterprise data management system 10, such as a SAP (RTM) system, comprising memory 12, central processor 16, and data processors 14-n. Each data processor processes an interval of data and outputs results stored in the memory. The central processor selects set of data-processors to process the data intervals for program instances (queries) requested by user 18-n. If system load is greater than a threshold, the central processor reduces the number of processors in the set. Central processor 16 also monitors total number of processors and allocates a subset of processors to achieve a predetermined load. It also alters the processors in the set upon detecting a change in their total number such that the proportion remains constant. By storing output of each processed interval central processor load-balances when receiving data-processing requests and alters load distribution responding to further requests or changes in availability of data-processors.

Title: Improvements relating to abandonment and recovery of pipelines
Inventor: CRUICKSHANK JOHN DUNCAN
IPC: F16L1/235
Filed: 2013-02-06
Abstract: A method of abandoning a pipeline during subsea pipelaying comprises suspending the pipe string from a tendon element of an abandonment string and engaging further tendon elements to an upper end of the abandonment string while lowering the pipe string to a handover depth. A tendon element comprises a tensile load-bearing member extending between end connector formations and at least one sleeve removably mounted around the load bearing member. At the handover depth, tension is applied via a wire to the top of the pipe string at an acute angle to the launch axis. This deflects the pipe string from the launch axis into axial alignment with the wire to transfer the weight load of the pipe string to the wire, whereupon the abandonment string can be decoupled from the pipe string. Recovery of the pipeline from the seabed can be effected by a reverse process.
